Description: SUNBIM r Energy Regulator is used to control and cut down energy consumption by up to 50 percent. The regulator allows drying cabinets, wash boilers, hot plates, and warming cupboards and similar equipment by heating from zero to full and set at the turn of a simmering, quick boiling, frying or jam making at appropriate positions. It has a snap action switch opens and closes the load circuit at precise time intervals. The proportion of the time `ON' to `OFF' can be varied, regulating the average power input and assuring a smooth output of heat. There are ten arbitrary divisions from `ON' to `FULL' on the scale marked on the control knob. It is rotatable both ways and definite steady holds on off and full positions. The entire switch mechanism is mounted on heat resistant bakelite and adequately covered to withstand temperature conditions where it is designed to function. Variations of ambient temperature of up to 850ºC and compensation for voltage fluctuations of up to - 15 percent are both automatic. Within these limits the rate of heat output for cooking operations will not be affected once the switch is set.
